T 0 all whom 1' 25 may concern:

Be it known that 1, Aaron Hemimxcnn." a citizen of the United States, and a resident of Hanover, in the county of Washington and Qtate of Kansas, have invented certain new and useful Improvements in Cultivators, of which the following is a spccifiea-, tion.

My invention is an inmrovement in cultivators, and consists in certain novel constructions and combinations of parts hereinafter described and claimed.

Referring to the drawing forming a part hereof, Figure 1 is a plan view of the improvement. Fig. 2 is a side elevation of one of the plows. Fig. 3 is a rear view of a disk and the manner of mounting the same. Fig. 4 is a similar View of a modified form of mounting, Fig. 5 is a modification where in a shovel is used instead of a disk. Fig. 6 is a side View partly in section of a straight mounting for the shovel. Fig. 7 is a plan View of a modified form. Fig. 8 is a side View of the same,'Fig. 9 is a detail perspective view of the connection between the axle of the cultivator and the plow, Fig. 10 is a reduced plan view of a modified form of frame, and, Fig. 11 is a plan view of a cultivator frame with the improvement attached.

In the present embodiment of the invention, two plow supporting frames are provided, each consisting of a spbstautially triangular frame 1, the base of the triangle being at one side of the frame, and the apex at the other.

At one of the acute angles of the triangular frame is arranged a bracket 2, provided ,at its free end with spaced lugs ttlt'll pro vided with an opening for receiving a pin 4, which is also adapted to pass through a lug 5, received between the bearings and provided with an opening. the said lug being integral with a casting 6 having an openingtherethronghfor receiving a stub shaft 7 on the cult .idl'. a set screw 8 and a key 8 being provided for preventing movement of the casting longitudinally of the stub shaft, and the stub shaft is provided with a key 8 for preventing rotary movementwith respect to the casting.

A handle 9 of ordinary construction is connected with the base on the triangular frame, ar d on the side opposite the bracket 2 before mentioned. integral are shaped bearings 10 are provided, the said bearings being arranged one behind the other and each provided with a longitudinal series of opduingr 11, for a purpose to be presently describe". The above mentioned side is also provided with spaced bearings 11? one at the apex of the triangular base, one at the acute angle opposite the bracket 2, and the other intermediate the first two mentioned. The cultivator disks 13 are journaled on to shafts 14, which are secured in sleeves 15, each of which is provided with an upwardly extending lug 16, having one of its faces corrugated as at 17, and engaging a lug 18 having a similarly corrugated face, the lug 18 being secured to, or integral with the lower end of the shaft 19, which is arranged in a sleeve 20, provided with forwardly projecting arms 21,, 22, the arms embracing the cultivator frame, and being retained in PO lilUIl by a bolt 23, pass ing through openings in the ends of the arms, and one of the bearings 12 before mentioned and other bolts 23 passing through holes ll in arcs 10.

A collar it. is arranged on the shaft 14 before mentioned, the said collar having its outer face shaped to fit the inner face of the disk, and being provided with a recess 2- for reccivingthe end of the sleeve, and a second collar 26 is also arranged on the shaft for engaging the outer face of the disk. the said collar having its inner face shaped to fit the outer face of the disk, and both collars are retained in place by a nut threaded on to the end of the shaft. A set screw 28 is thr aded through the sleeve 15 for engaging the shaft 14 to prevent rotation thereof with respect to the sleeve.

The lugs lti and 18 before mentioned are circular in shape and the lug 16 is provided with a bolt 29, projecting from the center thereof, which traverses a central opening in the lug 1S, and has a nut 30 threaded thereon. for retaining the disk 13, in position.

disk 13, may be rotated to vary theinelinartion of the disk with the perpendicular.

The shaft 15) before described is provided adjacent to the disk 18 with a collar 31, se-

provided on its upper face with oppositely arranged lugs which are adapted to be received in notches 34 in the sleeve 20 in which the shaft is arranged. Aset screw 35 traverses the sleeve and engages the shaft It is obvious by loosening the nut 3d, the

cured in position by a set screw 32, and i 2 scenes 5 in place by a set screw 38.

It will be evident that by loosening the set serew 38, and lowering the shaft to bring the lug out of engagement with the notch, the shaft may be rotated to vary the a of the shaft letwith the frame.-

In the modified form shown in Fi l, the lower end of the shaft 19 is provided with a knuckle 39, which is received between the spaced lugs 40, on a sleeve similar in all 5 respects tothe sleeve 15 before described,

anu provided with a set screw 28. A bolt etLtraverses the lugs and the knuckle, and the upper ends of the lugs are rounded as at 42 on the arc of a circle whose center is the 52 0 bolt ll, and the knuckle is provided with are shaped shoulders 43 against which the rounded ends abut. A set screw {t4 traverses one of the lugs J;0, and engagesthe knuckle for retaining the sleeve in its adjusted posi- 'tion: lV-hen it is desired to use shovels instead of disks, the construction shown in Fig. 5 may be made use of. With this construction, the lower end of the shaft 19 is pro ided with a box 45, having a longitudinal recess and a vertical passage at When the shovel 47 is to be supported a curved beam, the beam has one of its ends inserted in the longitudinal recess of the box 45, and secured in place by a pm t9,'and the other end has pivoted thereto,

a'yokei 501, the arms of the yoke being arranged on each side of the beam, and the plow 47 is secured to the edges of the yoke. The :ends lof the arms of the yoke are con- 40 nected' atlthe front of the beam as at 51,

andapin52 is providedwhich is adapted to traverse ,one of a series of openings in the arms/of the yoke, and an opening in the beam. By inserting the bolt in different openings; the angle of the shovelwith respect to the beam may be varied.

When a straight beam is used, as shown in Flg. 6, the said beam 54: is provided with a longitudinal series of alined openings 55, the shovel 4E7 ben'ig secured. to the lower front 'edgebf the beam, The beamis inserted in the vertlcal passage l6, and bolts 56, 57 are I inserted through the openings 55, and registering openings in the box. It is evident 55 that by placing the bolts 56, 57 in different opening theshovel 47 may be'adjustcd vertically with respect to the box.

In the construction shown in Figs. 7 and 8, the frame 1 is provided with airs of op- -p0sitely arranged lugs 60, provi ed .at their shaft 19, before mentioned, and bolts 64, pass through the openings in the endsof the lugs, for securing the parts in their adjusted position, the bolts G-t being provided with a nut 66.

The bolt 65 is engaged with one of the openings 62, this permitting adjustment of the bearings which support the disks. In Fig. 9 is shown mechanism for adjustably connecting the plow wit-lithe axle 67 of the cultivator, this mechanism comprising a pair of spaced plates 68, provided with registering recesses (39 for receiving the axle, and with openings 70 on each side of the recess for bolts 71, which secure the plates together.

A bar 72 ispivoted between the plates as at 73, the one end of the bar being rounded and provided with a longitudinal series of openings 74, and the other end is provided with a single opening 75, adaptedto register with openin 's 76 in the plates, when the bar is in the position shown in Fig.- 1, and a pin 77 is passed through the registering openings. The other end of the bar is provided with oppositely projecting lugs 78, adapted to engage theedges of the plates, to limit the swinging movement of the bar, and the platesare connected together at their outer ends as at 79. y

The rounded end 'of thebar 72 is inserted in a holder 80', which passes through a bearing 81 on the triangular frame 1 and is retained in position by means of a cotter pin passing through one'of the holes fat. This connection may be made rigid by turning the bar 7 2 so that the hole 7 5 registers with the openings 76 after which the pin 77 is inserted through the registering holes.

In Fig. 10 is shown a modified form of frame comprising a plate 85, bent in step form as shown, to form three parallel ofl'set portions 86, to each of which is secured a bracket 87, comprising a straight portion secured to the bar and an arc-shaped portion 88 provided with a series of openings 89. The straight portion is also provided with an opening 90. The opening 90 and oneof the openings 89: are adapted to receive bolts whereby to secure thearms 9.1, 2?, before mentioned.

A, loop 91 is arranged on each or Lllv:

frames to which isattachedthe apparatus i for raising and lowering the frames.

The cultivator frame which may be of any suitable construction is provided with stub shafts 7 projectinglaterallyfrom the frame in front of the axle,and the casting G on the triangular frame. receives the'isaid' stub shafts. The trian ular frame is also connected to the axle of the cultivator by means of the mechanism shown in Fig. 9, the plates 68 being clamped upon the axle 67 'as showy. in Figs. 9 and 11. i
